Sarah T. Hughes: Her Influence in Texas Politics
Access:
Use of this item is restricted to the UNT Community
Conservative males traditionally dominated Texas politics. In 1930, however, Sarah T. Hughes, a liberal woman from Maryland, began a spectacular career in state politics despite obstacles because of her gender and progressive ideas. First elected to the Texas Legislature in 1930, she remained active in politics for the next fifty years. Hard work, intelligence, and ability allowed her to form solid friendships with Texas's most powerful politicians. She became the first woman in Texas to hold a district judgeship, the first woman from Texas appointed to the federal bench, and the only woman to swear in a U.S. president. Hughes profoundly influenced state politics, challenging the long-standing conservative male domination. She helped to create a more diverse political field that today encompasses different ideologies and both genders.

Alternative Information Processing Formats for Overcoming Information Processing Deficits in Senior Adults
Access:
Use of this item is restricted to the UNT Community
The objective of this study was to examine the effectiveness of alternative advertising presentation formats, and the quantity of information presented in advertisements in overcoming possible information-processing deficits in senior adults that could affect their recall of ad attributes and brand name, the cognitive responses generated, and attitude toward the ad. In addition, the study examined the effectiveness of retirement status as a classification or segmentation variable in comparison with the use of the more traditional classification variable, chronological age. A convenience sample of senior adult volunteers from church groups, social clubs, and civic organizations from the local area were randomly assigned to one of nine experimental conditions. The experiment utilized a simulated magazine to test the effects of presentation formats (3 levels), and quantity of information (3 levels) on senior adult's recall, cognitive responses and attitude toward the test ads. Covariates (gender, wealth, education, activity level, health, and income) were used to reduce variance. The findings clearly indicate that the presentation format of the can ad adversely affected the memory of some senior adults. In addition, the results were significantly different across the different age levels. Retirement status was less beneficial than chronological age in the current study, but …

Retention and Attrition of Doctoral Candidates in Higher Education
A number of studies have been conducted on the attrition rates of undergraduate and graduate students. However, the body of knowledge concerning attrition for doctoral students, especially those who have attained the level of “all but dissertation” (ABD), is limited. The purpose of this research was to examine retention and attrition factors of doctoral candidates from a typical Higher Education Doctoral Program (Research II Public Institution) who were admitted to candidacy from 1991 through July 2000. Participation of the subject population was limited to those who had attained the level of ABD--those who had previously fulfilled the residency, coursework, foreign language or tool-subject requirements, and successfully completed the comprehensive/qualifying exams. This population included current ABDs, previously attrited ABDs, and graduates of the degree program. The research study was qualitative and intended to identify the effect of specific, predetermined factors that may have influenced or affected the progress of current, previous, and graduated students towards the doctoral degree in higher education. This study obtained responses to questions from the questionnaire/survey instrument concerning factors that affected program completion or attrition. Students had the opportunity to elaborate on factors from their dissertation, advisement, and personal, financial, and employment experiences that affected their ability …

The Developmental Stages of Concern of Teachers Toward the Implementation of the Information Technology Curriculum in Kuwait
Change is best carried out by individual teachers, and, thus, identifying and resolving teachers concerns about an innovation is imperative in guiding the change process to a successful point of implementation. The purpose of this study was to identify concerns that teachers experienced when implementing the Information Technology curriculum in all intermediate schools in Kuwait and to examine the relationships among teachers reported stages of concern and other factors, such as gender and experience. The stages of concern, one dimension of the Concerns-Based Adoption Model (CBAM), was applied to reveal teachers concerns. The Stages of Concern Questionnaire (SoCQ) and a demographic survey were completed by 248 respondents. The SoCQ measures seven stages of concern that reflect three dimensions: self (awareness, informational, and personal); task (management); and impact (consequence, collaboration, and refocusing Group profile analysis revealed that teachers had four high concerns related to collaboration, personal, refocusing, and informational stages. Teachers also reported low concerns at the management and awareness stages. Both females and males reported collaboration as their greater concern. Teachers with more years of experience reported higher impact concerns. The analysis of individuals peak concerns revealed that the majority of the respondents were adopters of the innovation. The analysis …

Work in the calling in Max Weber's Protestant ethic thesis
Access:
Use of this item is restricted to the UNT Community
Objectives. Scholars have debated Max Weber's theory of the relationship between religion and capitalism for almost 100 years. Still, the debate is clouded by confusion over Weber's claims about religious doctrine and over the supporting evidence. The purpose of this study is to clarify Max Weber's claims regarding the concept of the calling and the related "anti-mammon" injunction and concept of "good works" and substantiate with historical evidence the religious doctrine Weber describes. Methods. Comparative analysis of early Protestant Lutheran and Calvinist documents from the sixteenth and seventeenth centuries was used to flesh out a history of ideas to determine whether evidence exists to support Weber's claims related to religious doctrine. Results. Historical analyses revealed that the concept of the calling pre-dated Luther in the Bible. Luther's innovation was not in his use of the word beruf but in his application of the concept of the calling to the common people and his teaching of that idea. The idea of sanctified work was key in both Lutheran and Calvinist documents. There was an increased emphasis on work and encouragement to accumulate wealth in Calvinist documents. Conclusion. Weber's etymological evidence surrounding Martin Luther's use of the word beruf in his German …

Diphosphine Ligand Activation Studies with Organotransition-Metal Compounds
Access:
Use of this item is restricted to the UNT Community
Thermolysis of CoRu(CO)7(m -PPh2) (1) in refluxing 1,2-dichloroethane in the presence of the diphosphine ligands 2,3-bis(diphenylphosphino)maleic anhydride (bma) and 4,5-bis(diphenylphosphino)-4-cyclopenten-1,3-dione (bpcd) furnishes the new mixed-metal complexes CoRu(CO)4(μ -P-P)(μ -PPh2) [where P-P = bma (3); bpcd (6)], along with trace amounts of the known complex CoRu(CO)6(PPh3)(μ -PPh2) (4). The requisite pentacarbonyl intermediates CoRu(CO)5(μ -P-P)(μ -PPh2) [where P-P = bma (2); bpcd (5)] have been prepared by separate routes and studied for their conversion to CoRu(CO)4(μ -P-P)(μ -PPh2). The complexes 2/3 and 5/6 have been isolated and fully characterized in solution by IR and NMR spectroscopy. The kinetics for the conversion of 2→3 and of 5→6 were measured by IR spectroscopy in chlorobenzene solvent. On the basis of the first-order rate constants, CO inhibition, and the activation parameters, a mechanism involving dissociative CO loss as the rate-limiting step is proposed. The solid-state structure of CoRu(CO)4(μ -bma)(μ -PPh2) (3) reveals that the two PPh2 groups are bound to the ruthenium center while the maleic anhydride π bond is coordinated to the cobalt atom. Thermolysis of the cluster Ru3(CO)12 with the bis(phosphine)hydrazine ligand (MeO)2PN(Me)N(Me)P(OMe)2 (dmpdmh) in toluene at 75°C furnishes the known clusters Ru4(CO)12[μ -N(Me)N(Me)] (9) and Ru3(CO)11[P(OMe)3] (10), in addition to the new …

Effects of Reinforcement History on Stimulus Control Relations
Access:
Use of this item is restricted to the UNT Community
Ray (1969) conducted an experiment on multiple stimulus-response relations and selective attention. Ray's (1969) results suggested that stimulus-response relations function as behavioral units. McIlvane and Dube (1996) indicated that if stimulus-response relations are behavioral units the effects of environmental variables on stimulus-response relations should be similar to the effects of environmental variables on single response topographies. This experiment analyzed the effects of reinforcement history on the probability of stimulus-response relations with differing reinforcement histories. In separate conditions random-ratio schedules of reinforcement were contingent on each of four discriminated responses. To assess the effects of reinforcement, during test conditions stimuli controlling different topographies were present concurrently in composite form. Results show that reinforcement history affects the probability of each response topography and that the association between response topographies and their controlling stimuli tends to remain constant throughout variations in reinforcement probability.

Economic Development, Social Dislocation and Political Turmoil in Sub-Saharan Africa: A Pooled Time-Series Analysis and a Test of Causality
This study focuses on economic development and political turmoil in post-independence Sub-Saharan Africa. There has been a resurgence of interest in the region following the end of the Cold War. In 1997 U.S. president Bill Clinton took a 12-day tour of the region. In 1999 the U.S. Congress (106th Congress) passed the Growth and Opportunity Act and the Hope for Africa Act, designed to encourage political stability and economic development in the region. Although most Sub-Saharan African countries attained independence from colonial rule in the 1960s, more than 30 years of self-government have brought little economic development and political stability to the region. This study attempts to analyze, theoretically and empirically, the relationship among economic development, social dislocation and political turmoil. Social dislocation, as defined in this study, means "urbanization," and it is used as an exogenous variable to model and test the hypothesized causal relationship between economic development and political turmoil. This study employs pooled cross-sectional time-series and seemingly unrelated regression analyses, as well as Granger-causality, to examine the hypothesized relationships and causality in 24 Sub-Saharan African countries from 1971 to 1995. The results confirm the classical economic development theory's argument that an increase in economic development leads to …

Effect of Engineered Surfaces on Valve Performance
Access:
Use of this item is restricted to the UNT Community
Performance of air operated valves is a major maintenance concern in process industries. Anecdotal information indicates that reliability of some high maintenance valves has been improved by using an ion deposition process to achieve engineered surfaces on selected components. This project compared friction for various surface treatments of selected valve components. Results indicate valve performance may be slightly more consistent when an engineered surface is applied in the valve packing area; however surface treatment in this area does not appear to have a dominant affect on reducing valve friction. Results indicate a linear relation between stem friction and torque applied to packing flange nuts, and even after a valve is in service, controlled packing adjustments can be made without significantly changing valve stroke time.
